Which sensor to use for detection of Humans Climbing Poles

My Use Case

 

Our client is in Power Generation business. There have more than 3000 poles to transfer power from production to power grid. The distance between each pole is 400 meters. Most of the wires are having active current, but the ones at the low level are used for earthing and dont have any power supply.

 

The line passes through remotest areas of India and consequently, the locals cut the Earthing wire (no active current) and sell them in market. Motion detection camera is one of the option but that creates false alarms. I am looking for a sensor where in any human is trying to climb the pole, the camera gets active and takes snap of the user trying to climb.

 

What kind of sensor can be used for this use case? We need to detect it from the proximity of 5 meters.

 

The image of the pole is here: https://blogs-images.forbes.com/stevensalzberg/files/2014/08/670px-power_lines.jpg

    This is already done in industry. The presence of the electric fields means the best solution will be fiber optic sensing. Fiber is immune to EMI. If you are serious about it, you can message me on here…

    The motion scene camera connected to image recognition to look for a person. That may be one solution. Also if you cap sense where you are looking for a signature of a human body, this would take some…

    Ya, I wish, but the issue with IR is that it makes false alarms as even birds are routine visitors.

    An infrared motion detector should work day or night.
